I decided to book AA Premium Economy on the FCO-DFW flight for our upcoming trip (April/May 2022) to Italy. Business on American would take 300K miles per person. We could have flown on British Airways in Business for a mere 57.5K miles, plus over $400 per person in fees. I'll take Premium Economy on American over BA Business.
With that said, I've never actually flown in American's Premium Economy cabin. If you have, please let me know what to expect!
